The AIMS Laboratory (Advanced Instrumentation for Molecular Structure) was established in the summer of 2005 and houses several mass spectrometers.

Mass Spectrometry is one of the key techniques employed in structure determination. Obtaining the mass spectrum of a pure compound can take much less than a minute and minute quantities are required. Elemental compositions of small ions may be accurately determined and the masses of proteins weighing hundreds of kilodaltons may be obtained. Mass Spectrometry is also one of the most sensitive techniques and is employed for quantitative analysis in many fields.
